"I want to mount a camera directly to a wall of my house or the soffit. Would I need to get a mounting bracket or a junction box?"
This is one of FAQs we get asked quite regularly, so here we will have a quick look at the pros and cons of using a junction box as well as the installation steps.
Most cameras (including Hikvision and Dahua) have a short lead attached to the body of the camera which you would need to accommodate on installation.
Whilst it is normally ok as there is a small grove you can remove from the camera's base to feed the cable through, it can present a challenge for if the camera is to be mounted on a hard surface like brick, masonry or stucco.
It is for this reason that many people choose to mount the camera on a junction box or wall-mount bracket. Not only it ensures a tight connection of the camera to the wall, but it also provides waterproofing for the RJ45 cable and any power cables and additional protection against tampering.
So, the short answer is that yes, you can mount a camera without using a junction box or even a bracket (depending on the model), but you would just make the process needlessly complicated and the end result may be not aesthetically pleasing.
If you've decided that you are going to mount your camera on a junction box, here is how to do this.
Step 1 - Fix a Drill Template Sticker to the wall/ceiling
Fix the drill template sticker (included with most mounts), to the place where you want to mount the camera.
NB! From personal experience, if you use a Hikvision camera, it may actually be easier to just use the sticker for size reference and then use the actual bracket and a pencil to indicate where to drill the holes.
Step 2 – Mount the junction box
Mount the junction box to the wall / ceiling as shown on the sticker.
Step 3 – Feed the cables through the holes
To ensure a watertight connection, put the cables through the rubber membrane.
Step 4 – Mount the camera
Plug the cables into the camera and mount the camera on the junction box. Tighten up the screws and wipe the lens of any fingerprints if necessary.
